B (A) Valvate Corolla - The aestivation in corolla (petals) of Calotropis is valvate. (B) Funnel shaped corolla (Infundibuliform) Datura and several other members of the convolvulaceae family. (C) Papilionaceous flower - The posterior large petal is called a standard petal, two lateral ones are called wing petals and two fused inferior ones are called keel petals. This type of arrangement of petals is called vexillary. (D) Imbricate aestivation - In imbricate aestivation the margins of sepals or petals overlap one another but not in any particular direction as in cassia and gulmohur.
